I "upgraded" to 5.5 a few days ago. I have a crash in Explorer every 10 minutes or so. Tried a 2nd download-no good. tried to overlay Windows again- same thing. In "Add/Remove Programs" there is no option to uninstall. PLEASE don't tell me I have to do a fresh install of Windows!!!! Sinec 5.5 is new, I didn't see ant patch files yet. I hate my life
